Abstract
The invention relates to a flexible hose line, in particular, a high-pressure hose line which is subjected to a pressurized forming process, preferably for variable levels of pressure. Said flexible hose line consists of several layers, at least one of which is configured as a reinforcing layer. The hose line is characterised by an inner layer ( ) with a profile which can be elastically stressed in at least the longitudinal direction of the hose. Said inner layer is the only layer whose length can be modified. The hose line is also characterized by a reinforcing layer ( ) which is configured to absorb the tensile forces acting on the hose in the longitudinal direction, by a compensation zone ( ) which is located between the inner layer ( ) and the reinforcing layer ( ) and which compensates the movement of these two layers in relation to one another and acts as a radial support for the inner layer ( ) on the reinforcing layer ( ); and by connecting areas ( ) for connecting the inner layer ( ) to the reinforcing layer ( ). Said areas are used to define the variable length of the inner layer ( ) as a predetermined utilization length, determined by the length of the reinforcing layer ( ) between the connecting areas ( ).
